Accumulated road salt, thick mud, oil, and harsh winter chemicals on a vehicle's underbody lead to accelerated rust formation and costly suspension repairs over time. Cleaning the chassis with standard pressure washer nozzles forces you to bend down, crawl on damp driveways, and guess where you are spraying. That is why the RIDGE WASHER Pressure Washer Undercarriage Cleaner, with Foam Cannon | 16 Inch Undercarriage Washer, Under Car Cleaner with Straight Extension Wand, 4000 PSI has become an indispensable detailing attachment for car owners, truck enthusiasts, and fleet managers across the United States. Designed to combine high-pressure chassis rinsing with dense foam application, this mobile water broom makes vehicle underbody maintenance fast, thorough, and effortless.
Featuring a heavy-duty 16.1-inch spray bar equipped with four high-pressure nozzles and smooth-rolling casters, this undercarriage attachment glides fluidly across concrete and asphalt driveways. Engineered to operate efficiently within a 1500 to 4000 PSI pressure range (performing best at 2500 PSI or higher), the spray nozzles blast upward to dissolve caked-on grime, oil deposits, and corrosive road salt from trucks, SUVs, commercial trailers, and low-clearance sedans. The included foam cannon attachment pairs directly with the system, allowing you to coat the chassis in rich, clung cleaning foam to loosen tough dirt before high-pressure rinsing.
Built with industrial-grade brass and stainless steel components, this versatile set includes both straight extension wands and a 45-degree curved wand for optimal reach under deep frames. Quick-connect 1/4-inch brass fittings ensure rapid setup with your existing pressure washer gun without fluid leaks or pressure drops. The dual-purpose design also functions as a surface water broom for sweeping away leaves, sand, and debris from garage floors, patios, and driveways. Safeguard your vehicle's frame against rust, eliminate tedious under-car crawling, and keep your vehicle's underbody pristine with a heavy-duty 4000 PSI undercarriage cleaner built for total detailing convenience.
